Mark internal stdlib functions with attribute_hidden [BZ #18822]
Mark internal stdlib functions with attribute_hidden to allow direct
access within libc.so and libc.a without using GOT nor PLT. __realpath
is hidden with libc_hidden_proto and libc_hidden_def since the exported
realpath is an alias of __realpath.
[BZ #18822]

* misc/efgcvt_r.c (cvt_symbol_1): Add libc_hidden_def (local).
* stdlib/canonicalize.c (__realpath): Add libc_hidden_def.
